A theoretical consideration supports the results and also reveals that the part of secondary flow in the nozzle, which is related to the upstream boundary layer, depends upon the configuration of the nozzle. 3 The observed boundary layer behavior was compared with the predicted flow by a three-dimensional laminar boundary layer theory, and good agreement was obtained. 4 The measurements showed the end-wall boundary layer rolling up at the suction-surface end-wall corner of the cascade. The mechanism of the rolling up is explained.Read More
